I have, for many years, fished a caddis pupa soft hackle pattern which has worked wonderfully for me and others. If I can locate a picture, I will post it as well.

After seeing a pattern by PlanetTrout, I thought I would morph my soft hackle pattern into the next stage of a caddis, a partially emerged, perhaps crippled caddis with the attached shuck.

Cannot speak to effectiveness, as have not had a chance to fish it, but look forward to doing so.

ere is Hans Weilenmann's photo of the soft hackle version I alluded to:
